People may not be aware of it, and people may say if you have content available day one, why not put it onto disc? What goes out on disc, it takes about 12 weeks to debug and certify and get into the trucks to go out into stores," he explained. "That gives us a period of 8 to 12 weeks where we can make content, but we can't put it onto the disc because it's already out there. But we can insert it digitally, day one."

In other words, the team can have up to three months of time after the game is finished, getting pressed onto discs, and tested with Microsoft; in that time content is being created for the game. This was how the character Zaeed was created; they knew the character was going into the game, and they knew they wanted him available on the first day. He was simply being worked on after the code went out to be pressed onto discs.

Ok, so basically it has nothing to do with making an additional buck. I'm pacified and looking forward to more Day One DLC!
